distance = time * speed
1 mile = time * 3.5 miles /56 minutes
so time = 56 minutes/3.5 = 16 minutes
Answer:
6.40
Step-by-step explanation:
8 decreased by 20% is 6.40
I suppose you want to solve the equation for m. To do so, multiply both sides by 8m to get

Now divide both sides by 3 to get

304020 just say it in your head it will make sence
x + x-5 + x +23 = 180
combine like terms:
3x +18 = 180
subtract 18 from each side:
3x = 162
divide both sides by 3
x = 162 / 3 = 54
Angle x = 54 degrees
Angle x-5 = 54-5 = 49 degrees
Angle x +23 = 54 +23 = 77 degrees
